Coverage and gaps
We'd rather be honest than look complete. Right now we list 706 household hazardous waste listings in 51 of 51 states + DC. This is a starter dataset: 28 of those states have fewer than ten listings, and most counties in the country are not listed yet. A listing is one program — usually open only to residents of one city or county — not statewide access.
- Types: 538 permanent drop-off sites, 140 collection events, 8 mobile collections, 20 home pickup programs, 0 retail take-back locations listed by an agency.
- Verification: 599 read directly from the official page; 107 checked only through a web search restricted to the agency's own website, because our build tools could not open the page. Search-only listings have not had their hours, fees, materials or access rules field-checked — each listing says which method was used and when.
- Map pins: 597 exact or street-level (these are the only pins drawn on maps); 86 known only to a ZIP or city center and 3 known only to the county (no map pin yet — we link an address search instead); 20 with no position at all (home pickup programs).
- Events: an events page does not mean every county has an upcoming date. Many programs announce dates late; when the official page only says “annual, date to be announced,” so do we.
- OpenStreetMap supplement: 0 listings. Not yet fetched — the Pass 1 build environment could not reach any Overpass API endpoint (refused by the sandbox network proxy). Run npm run data:fetch where Overpass is reachable.
Events or pickup only (no permanent site listed yet): Connecticut, District of Columbia, Hawaii, Rhode Island.
Top 50 metro areas
We track the 50 largest US metropolitan statistical areas (U.S. Census Bureau, Metropolitan and Micropolitan Statistical Areas Population Totals: 2020-2024 (Vintage 2024)). A metro counts as having a local permanent option when at least one permanent drop-off site (or agency-listed retail take-back) is listed in one of its core counties — that does not mean it is open to everyone: most are residents-only, and many need an appointment. 45 metros have a local option, 2 only a nearby one (within 30 miles), 2 only events, mobile collections or pickup programs, and 1 none we have listed yet.
